@Asha thank you - do you think long sleeve vest or short sleeve? Yeah that's the other thing, I don't want him to end up being chilly 😅
The temp will be a lot cooler by bedtime than you think. I would personally do a 1.5 tog with normal sleepsuit and vest. It's not like a 23 degree day in summer where the nights are warm too
I'm the same she likes to be warmer so I'm still putting her in a 2.5 tog with short vest and babygrow. Her room is often cooler than ours
I would go with a 1.5tog and vest as the temp will drop overnight you can always add a babygrow during the night 🌙
